The noise generated by the reducer of a European-style steel wire rope electric hoist on the outer frame can be attributed to several key factors, primarily related to lubrication, gear wear, and bearing damage:

Lack of Lubrication:

If the reducer's gearbox or bearings are

not adequately lubricated, it can lead to excessive friction and wear. This lack of lubrication not only produces a high "humming" noise but also accelerates the deterioration of gears and bearings.

Solution: Ensure that the reducer is properly lubricated before use and that lubricants are replaced regularly during operation.

Gear Wear or Damage:

Over time, gears within the reducer can wear down or become damaged due to continuous use and high loads. This wear can cause irregularities in gear meshing, leading to increased noise levels.

Symptoms: A "clattering" sound emanating from the reducer may indicate worn or damaged gears.

Solution: Regularly inspect the gears for signs of wear or damage. Replace any gears that are no longer functioning properly to restore smooth operation and reduce noise.

Bearing Damage:

Bearings within the reducer are subject to high loads and can wear out or become damaged over time. This damage can cause the reducer to produce abnormal noises, similar to those heard when motor bearings fail.

Symptoms: A "rattling" or "grinding" noise near the bearings may suggest bearing damage.

Solution: Inspect the bearings regularly for signs of wear or damage. Replace any faulty bearings promptly to prevent further damage and reduce noise.
